This reminds me of Buckminster Fuller's book 'The Critical Path'. The first half is all about how you should careful record everything you do, the second half talks about how to write down everything you do.

Making an estimate all boils down to knowing yourself. How do you work? What is time consuming drudgery, what is exciting and engaging for you? How GOOD are you at breaking up a project into component parts?

I tend to go with flow charts sketched out by hand as my visual aid. I do my best to estimate how long each of those boxes will take me to complete. If it involves communicating with someone else or waiting on input, I automatically double the estimate for that box.

Tally up the times and apply the Scotty factor (X 3). That is the worst case scenario and that is the one I communicate to my customers. The people knowledge here is spot on: Beat your estimate and you are a hero, meet the estimate (through bad luck or unforeseen disaster) and you are a valued member of the team who delivers on time.

    [oiskuu]: Discipulus, from the edge or from the top?
    [Discipulus]: oiskuu from the top aka 0-0 coords
    [LanX]: edge or node?
    [oiskuu]: from each height difference, there's a fixed number of "moves right" - "moves left". So it's a number of combinations.
    [Discipulus]: I already know how much distinct paths exists but to demonstrate the property i want to have them all
    [oiskuu]: ie C(n, k); where n is height difference, k is position in the line
    [Discipulus]: infact there are 70 distinct path to reach the tale wich holds 70
    [Discipulus]: what i want is to compute them
